If they are not identical, there is a failure at run time,\nwhich manifests as either a kernel panic or thread getting killed.\n\next4_feat_ktype was setting the \"release\" handler to \"kfree\", which\ndoesn't have a matching function prototype. Add a simple wrapper\nwith the correct prototype.\n\nThis was found as a result of Clang's new -Wcast-function-type-strict\nflag, which is more sensitive than the simpler -Wcast-function-type,\nwhich only checks for type width mismatches.\n\nNote that this code is only reached when ext4 is a loadable module and\nit is being unloaded:\n\n CFI failure at kobject_put+0xbb/0x1b0 (target:
